We rounded up the 14 most luxurious yachts we could find. Some are concepts and may not materialize for a few years (if at all), others are probably on the seas as we speak. All are eye-catching and extremely pricey.

The Octopus comes with a pool, two helicopters, and a movie theater. If that's not enough, there's also a basketball court and recording studio.

Like any true luxury yacht, the Galactica Star also comes with a Jacuzzi, bar, and sundeck.

5. Recently, Heesen unveiled its Galactica Super Nova design, the largest superyacht the company has designed. It has a roughly 20-foot infinity pool on the main deck.
